Last Updated: July 2024

Overview

The Massey Ferguson 3690 is powered by a Valmet 612DS 6-cylinder turbocharged diesel engine with a displacement of 449 cubic inches, generating 168.8 horsepower at a rated RPM of 2200. It offers a choice of two-speed or four-speed power shift transmissions with 32 forward and 32 reverse gears. Key performance metrics include a maximum torque of 536.6 lb-ft at 1273 rpm with a 32.8% torque rise, hydraulic capabilities with a maximum force of 10,500 lbs at the hitch points, and fuel efficiency ranging from 17.74 Hp.hr/gal at standard PTO speed to 17.10 Hp.hr/gal at varying power conditions. The tractor is equipped with a foot pedal operated clutch, single wet disc brakes, and a 12V electrical system. It has a 28.4-quart coolant capacity cooling system and a three-point hitch (Category III). The operating weight is 13,835 lbs for the 2WD version and 14,960 lbs for the FWA (Front Wheel Assist) variant.
